This unit is was used a few times and just sat in the car, its about a year old and has no physical or mechanical defects. Comes with the unit, dashboard friction mount, 12v power supply with built in speaker, a garmin carrying case, usb connector so you can sync with your pc, and an external optional antenna that is great when the weather is bad so you dont have to wait for it to find the sattelite, it instantly connects. Im asking $250 plus shipping. These sell for over $500 new.
